The applicant, an assistant caretaker, alleged that her union breached its duty of fair representation under section 74 of the Labour Relations Act by refusing to file a grievance regarding a salary differential.
The differential arose from a merger of two school boards, where some former employees' salaries were red-circled.
The union obtained a legal opinion and concluded the differential was based on a factor other than sex, thus not violating section 32 of the Employment Standards Act.
The Board dismissed the application, finding the union's decision not to grieve was considered, based on legal advice, and not arbitrary, discriminatory, or in bad faith.
